UNITED STATES JOHN FRANKDOWELL, OF GLENDALE, CALIFORNIAL METAL BASE.

Application filed July 13, 1927. Serial No. 205,309.

This invention relates to metal bases of the type employed as afinishbetween a plaster wall and the floor.

An object of the invention is to provide a finish of this descriptionthat. will not permit the plaster to crack away from it at the line ofjunction between the plaster and the metal base. 7

Another object is to make provision for securing the metal base inposition without the fasteners showing.

Further objects and advantages will appear in the subjoined detaileddescription.

The accompanying drawings illustrate the invention:

Figure 1 is a sectional view showing a fragment of a wall or partitionwith metal bases, embodying the invention, secured in place, a floorjoist and flooring also being fragmentarily shown.

Figure 2 is a broken perspective view of the metal base.

In Figure 1 are shown a sub-floor 6, a plate 7 supported by thesub-floor and a wall member 8 on the plate Floorin 9 is supported on thesub-floor 6. Exten ing along the edges of the plate 7 and resting on thesub-floor 6 are furring members 10. Secured to opposite edges of thewall support 8 by nails 11, or other suitable fasteners, are metal baseswhich are indicated, in general, by the character 12. The metal bases 12are also secured by nails 13, or other suitable fasteners, to thesub-floor 6.

The metal base 12 comprises an upper straight body portion 14 and isbent back upon itself to form an L-shaped member 15 which is turned backover the body portion 14-and which is secured along one edge to saidbody portion 14. The L -shaped member 15 is provided. along one edgewith an inwardly projecting flange 16, the L- shaped member 15 andflange 16 together forming a hook construction into which the plaster orcement of the wall, indicated at A, can flow when in a plasticcondition. The flange 16 is perpendicular to the straight body portion14 and, in this particular instance, the L-shaped member 15 extends inpart perpendicular to the body portion 14 and, in part, parallel to saidbody portion, but it may be of any other suitable shape. An importantfeature is the flange 16 which projects toward the body portion 14. Thenail 11 passes through the straight body portion 14.

itself and extends downwardly from the L shaped member 15 to form alower straight body portion 17 adapted to lie along the outer face ofthe furring member 10. J oined,

to the lower-edge ofthe body portion 17 is a horizontally projectingflange18 through which the nails 13 pass so as to firmly secure themetal base to the sub-floor 6. The flange 18 is adapted to underlie theflooring 9, the nails 13 being driven into place before the flooring islaid. If desired, after the flooring is laid, a molding or carpet strip19 may be secured to the filming 10 by nails 20 or other suitablefasteners. Thenails20 pass through the lower straight body portion 17.

To use the metal base, it will be secured in position to its supports,as described above, and the plastic cement or plaster A will then beapplied in a well known manner to the lath, indicated at 21, and to thatpor-v tion of the metal base that lies above the L-shaped member 15 in amanner to key some of the plastic material beneath the flange 16. Theplastic material will be finished off at the surface flush with theouter edge of the flange 16.

The plaster will not break away from the flange 16 where it joins saidflange even though a certain amount of relative movement occurs betweenthe sub-floor 6 and the wall.

I claim:

1. A base formed of strip metal and comprising an upper body portion,the strip bent upon itself to form a member bent over said upperbodyportion, a flange extending along the edge of the bent over member andprojecting inwardly toward the upper body portion, the flange beingapproximately perpendicular to the plane of the upper body portion, theflange and bent over member to gether constituting a hook-shaped memberto key cementitious material, a lower body portion extending downwardlyfrom the bent over member, and a horizontally projecting flange joinedto the lower edge of the lower body portion.

2. A base formed of strip metal and comprising an upper body portion,the strip bentupon itself to form a member bent over said upper bodyportion, a flange extending along the edge of the bent over member andprojeeting inwardly toward the upper body portion, the flange beingapproximately perpendicular to the plane of the upper body portion, theflange and bent over member together constituting a hook-shaped memberto key eementitious material, the metal of the flange bent back uponitself and extending downwardly from the flange to form a lower bodyportion, and a horizontally projecting; flange joined to the lower edgeoi the lower body portion.

3. The combination with a sub-floor, flooring thereon and a wall member,of a base formed of strip metal and comprising an upper body portion,fasteners extending from the upper body portion into the wall member,the strip bent upon itself to form a member bent over said upper bodyportion, a flange extending along the edge of the bent over member andprojecting inwardly toward the upper body portion, the flange being,approximately perpendicular to the plane of the upper body portiom theflange and bent over member together eonstituting a hool -shaped member,lath secured to the 'all member, eemeutitious material mounted on thelath and extending beneath the flange, a lower body portion extendingdown 'ardly from the bent over member, a horizontally projecting flangejoined to the lower edge of the lower body portion and extending beneaththe edge of the flooring, and fasteners (attending from the lastmentioned flange into the sub-floor.

Signed at Los Angeles, Calif. this 6 day of June 1927.
